The two power point slides in this activity illustrate gas exchange in the lungs (external respiration) tissues (internal respiration). Each slide shows a cell (either tissue cell or alveolar cell) at the top and a blood vessel (with plasma and RBC) below. To complete the activity: 1. Determine which illustration is external respiration and which is internal respiration. You must do this first so that you wil use the correct description to label each slide. 2. On each slide, drag the cell name (either tissue cell or alveolus) onto the cell at the top. 3. Read the descriptions below, one for external respiration and one for internal respiration, and as you do, drag the numbers on each slide to their correct location on the illustration. External respiration During external respiration, the small amount of carbon dioxide transported in the plasma (1) quickly diffuses out of the blood down its pressure gradient. A small amount of oxygen (2) dissolves in the plasma. However, a majority of…
A patient has a tidal volume of 500ml, a breathing rate of 16 breaths/mm, a dead space volume of 150ml, and FRC (functional residual capacity) of 3 liters. Minute ventilation for this patient would be:
Describe the effects of Increasing frequency vs tidal volume on minute ventilation and alveolar ventilation. I'm confused about what type of effects it will cause.
